I inherited few vmware servers. They're 4 quad xeon servers with hyperthreading and 64 gb of RAM. The ESXI is an enterprised version. Some of the VM's are configured with 8 virtual processors and 8-24 gb of ram. About 8 VMs are running on each host. Are there advantages of using over 2 virtual processors? Is it necessary to allocate 24 gb of Ram to virtual machine.
